Aluminum-Clad Casement Windows – A Sustainable, Stylish, and Durable Choice for Your Home!

Key Features

Composite Construction for Durability and Aesthetics

Casement windows feature a solid timber core, typically made from FSC®-certified softwood sourced from sustainable Northern European forests, ensuring environmental responsibility. The exterior is protected by a robust aluminum cladding that shields the timber from harsh weather conditions, UV rays, and moisture, significantly extending the window’s lifespan by over 20 years compared to all-timber windows. This cladding requires minimal maintenance, needing only periodic cleaning with soapy water and annual oiling of hinges and handles.

Modern and Traditional Design Options

AURAPLUS: Characterized by clean lines, flush finishes, and a minimalist Scandinavian aesthetic, AURAPLUS windows are ideal for contemporary homes and modern architectural projects. The sleek design maximizes natural light and complements minimalist or Scandinavian-style interiors.

FORMAPLUS: Designed with traditional British architecture in mind, FORMAPLUS windows feature unique detailing, such as beveled edges and angled glazing beads, making them perfect for heritage properties, period homes, or classic-style builds. Optional glazing bars can enhance the traditional look while maintaining modern performance.

Superior Thermal Efficiency

Available with double or triple glazing, Rationel aluminum-clad casement windows offer excellent thermal insulation, reducing heat loss and supporting energy-efficient living with outstanding thermal performance. These windows are designed to meet the demands of low-energy buildings and Passive House standards, making them a sustainable choice for eco-conscious projects.

Enhanced Security

Aluminium-clad windows come equipped with security hardware that meets Secured by Design standards, including high-performance locking systems and optional laminated or toughened glass to enhance break-in protection. The aluminum cladding adds structural strength, making the windows more robust and burglar-resistant. The locking system allows secure ventilation by enabling a small gap for airflow while preventing further opening.

Versatile Operation and Ventilation

Aluminium-clad casement windows feature outward-opening sashes, available in side-hung or top-hung configurations, providing excellent ventilation control. The adjustable hinges and smooth-operating mechanisms ensure effortless handling, while the inbuilt friction brake allows secure positioning for ventilation. These windows can be used singly or in pairs within a common frame, offering flexibility for various design requirements.

Customization Options

This system offers extensive customization, with over 200 RAL color options for the aluminum cladding, available in satin, gloss, or matte finishes, and a variety of interior timber finishes (painted or stained) to match your design vision. Glazing options include obscure, frosted, acoustic, solar, or secure laminated glass, allowing you to tailor the windows for privacy, noise reduction, or thermal control. The windows can also be customized in terms of shape, size, and glazing bar patterns to suit any architectural style.
